Performance management method and electronic device

Abstract

A performance management method and an electronic device are provided. The method is applied to the electronic device with a system processor and includes: sensing a temperature of the electronic device and determining whether the temperature is greater than a first temperature setting value; when the temperature is not greater than the first temperature setting value, initiating a frequency increasing procedure; when the temperature is greater than the first temperature setting value, determining whether the temperature is greater than a second temperature setting value, where the second temperature setting value is greater than the first temperature setting value; when the temperature is greater than the first temperature setting value and is not greater than the second temperature setting value, initiating a first frequency reducing procedure; and when the temperature is greater than the second temperature setting value, initiating a second frequency reducing procedure or turning off the system processor.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This non-provisional application claims priority under 35 U.S.C. § 119(a) to Patent Application No. 108145413 in Taiwan, R.O.C. on Dec. 11, 2019, the entire contents of which are hereby incorporated by reference.BACKGROUNDTechnical Field[0002]The present invention relates to power performance management technologies, and in particular, to a performance management method in which an operating frequency is controlled through rapid reduction and slow increase and an electronic device.Related Art[0003]With the development of integrated circuit technologies, increasing requirements are imposed on functional specifications of integrated circuits, resulting increasingly complex and detailed design of the integrated circuits. Application of a system-on-chip (SOC) based on the circuit design on electronic product is extremely important. When operating at a relatively high frequency, the system-on-chip consumers more power, and correspondingly more ...

AI Technical Summary

Benefits of technology

The present invention proposes a method for reducing the temperature of an electronic device with a system processor that has a high temperature. The method includes sensing the temperature and adjusting the operating frequency of the system processor through gradual frequency reduction and frequency increase to reduce the temperature and maintain the device's best performance. The method can be implemented by an electronic device with a temperature sensor and a control module that adjusts the operating frequency according to the temperature readings. The technical effects of the invention include improving the safety and performance of electronic devices that overheat easily.

Problems solved by technology

With the development of integrated circuit technologies, increasing requirements are imposed on functional specifications of integrated circuits, resulting increasingly complex and detailed design of the integrated circuits.

Once there is an excessive temperature, the system-on-chip cannot operate normally, and even an entire system shuts down or is damaged.

However, a speed of a frequency-reduced electronic product is significantly lower than an original normal speed of the central processing unit, resulting in a lower computing speed of the electronic product.

Consequently, optimal performance cannot be maintained.
